SPECIFICATION forming part of Letters Patent No. 763,585, dated June 28, 1904.

' Application filed September 8, 1903. Serial No. 172,289. (No model.)

To alZ whom, it maby concern.-

Be it known that I, OTis E. ZIPP RER, a citizen of the United States, residing at Home, in the county of Echols and State of Georgia, have invented certain new and useful Improvements in Shingle-Machines; and I do hereby declare the following tobe afull, clear, and exact description of the invention, such as will enable others skilled. in the art to which it appertains to make and use the same.

This invention relates to machines for sawing shingles from blocks of wood; and it consists in, the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figurel is aplan view ofv themachine, portions of the turn-table and the devices connected with it being omitted. Fig.2 is a vertical section through the machine, showing the driving mechanism. Fig. 3 is an end view of the machine looking toward its driving-shaft. Fig. 4 is a plan view of a. portion of the turn-table and the mechanisrnconnected with it drawn to a larger scale. Fig. 5 is a sectiontaken on the line 00 m inFig.4.v a i A is the base-plate of the machine, and B is the sawtable, which is supported above the base-plate by distance-pieces b. a

C represents longitudinal bars secured to the base-plate and provided with bearings c at one end, in which the maindriving-shaftD of the machine is v journaled. A driving-pulley d issecured on the shaft D.

E E are two saws arranged above the sawtable, one at each side of the machine. Each saw E is secured on a vertical shaft 6, which is journaled in the base-plate and in the sawtable, and e is a driving-belt pulley secured upon the shaft 0. upon the driving-shaft D, and f representsthe belts which pass over the pulleys F and 6', so that the saws are revolved continuously. A wormGr is also secured on the middle part of the driving-shaft D and afiords a means for driving the turn-table.

H is the turn-table, whichis mounted on the.

turn-table shaft H, which is journaled in a Belt-pulleys F are secured vertical position in the base-plate and in a frame 9, which is supported above the turn wheel which gears in the said wheel I and which issecured upon an intermediate shaft J. The shaft J is journaled at one end near shaft J is journaled in a pivoted arm 7'. A worm-wheel y" is secured on the shaft J near the arm and is driven by the worm G on the main driving-shaft, hereinbefore described. One end of the pivoted arm j is journaled on a pivot is, which is secured to the base-plate,

'and its other end is pivoted to one arm of a bell-crank lever K, which is pivoted on a pin k, which also is supported by the base-plate.

Lis a hand-lever having its lower end pivoted to the base-plate, and M is a rod which is pivoted at one end to the hand-lever and at its other end to the other arm of the bellcrank lever K. A spring-actuated catch 17?. is

provided and carried by the hand-lever L, and

this catch engages with a notched bar on, projectingfrom the saw-table, so that the handlever. may be secured in diflferent positions.

i the wheel 2' in a bearing a", supported from the base-plate, and the other end portion of the.

N. is a brake-lever pivoted to the under side a of the saw-table and. arranged to press against the brake drum 7t.

N is a rod which is pivoted tothe free end i T or the brake lever at one end and which'has, its other end pivoted to the rod M. When the hand-lever is moved in one direction, the worm-wheel is lowered into gear with the worm and the brake-lever is moved away from the brake-drum. When the hand-lever is moved in, the reverse direction, the worm wheel is thrown out of gear and the turn-table is stopped quickly by the pressure of the brakelever. on the brake-drum. I

The turn-table H is provided with a series of rectangular pockets P around its periphery,"

and the blocks of wood from which the shingles are sawed are placed in these pockets. As these pockets and the devices for tilting the blocks are all alike, the illustration and description will be confined to one set of devices.

Two track-rings R and R are suspended from the frame g. The outer track-ring is provided with a raised portion 1" at oneside adjacent to one saw, and the inner track-ring R is provided with a similar raised portion 9" adjacent to the other saw.

S and S are hangers provided with rollers s and s at their upper ends, which run on the track-rings Rand R, respectively. Springs (1 are provided for pressing thesehangers downward, so that their rollers bear steadily on the tracks. J

T and T are two pointed dogs which are slidable in holes in the lower parts of the hangers Sand S, respectively. These dogs are pivoted to an arm U, which is slidable horizontally on the turn-table. The arm U has a'roller u at one end,'which works in astationary cam W, which is provided with a suitable groove to receive it. The cam W is secured to the frame g, and it operates to reciprocate the dogs at intervals as the turn-table is revolved. The groove of the cam is arranged so that the dogs are retracted when the block with which they engage is in the space between the saws, and the dogs are pushed out into engagement with the block after the block has moved downward in its pocket. A springw is provided for pressing the block downward in the pocket when the dogs release it.

This machine is shown as having two saws; but additional saws may be provided, if desired, at points intermediate between the two saws shown, and the tracks can then be provided with additional raised portions for operating the dogs at intermediate points.

' The operation of the machine is as follows: A block of wood is placed in one of the pockets and is pressed downward on the saw-table by the spring w. The table is started by means of the hand-lever, and as the block approaches one of the saws one of the dogs is raised by means of one of the hangers, which is operated by the raised portion of the trackring adjacent to the said saw. The saw cuts off a shingle as the turn-table continues to revolve, and the said shingle is thick at one end and thin at the other, because the bottom of the block has been inclined with respect to the plane of the saw-blade by the action of the said parts. After the shingle has been sawed oif the dogs are retracted so that the block is released and pressed downward in its pocket. The continued revolution of the turn-table causes the dogs to reengage the said block,

and before the block is operated upon by the other saw .it is inclined in the reverse direction by the raised portion of the other trackrequired, as hereinbefore described.

What I claim is 1. In a shingle-machine, the combination, with a turn-table, and its shaft; of a beveled toothed wheel and a brake-drum secured on the said shaft, a brake for engaging the said brake-drum, a main driving-shaft, a worm secured 0n the said driving-shaft, an intermediate shaft, a beveled toothed wheel secured on "the said intermediate shaft and gearing into the aforesaid wheel, a worm-wheel secured on the said intermediate shaft, a bearing supporting one end portion of the said intermediate shaft, a pivoted arm supporting the other end portion of the said intermediate shaft, a pivoted bell-crank lever for operating the said arm and placing the said wormwheel into and out of gear with the said worm, a pivoted hand-lever, a rod connecting the said hand-lever and arm, and a second rod connecting the said rod with the said brake.

2. In a shingle-machine, the combination, with a rotary turn-table provided with a pocket for the block to be sawed, of two circular saws for cutting up the block, two stationary track-rings each provided with a raised portion arranged adjacent to the saw to which it pertains, hangers which run on the said track-rings, dogs operated alternately by the said hangers and engaging with the said hangers and provided with points for engaging with the end portions of the said block, and means for disengaging the said dogs from the block periodically.

3. In a shingle-machine, the combination, with a rotary turn-table provided with a pocket for the block to be sawed, of two stationary track-rings supported over the said table and provided with raised portions at prearranged points, hangers which run on the said track-rings, dogs which slide in holes in the lower parts of the said hangers and which engage with the end portions of the said block, and a radially-slidable arm supported by the said turn-table and having the said dogs pivoted to it.

4:. In a shingle-machine, the combination, with a stationary saw-table, and a frame arranged above the saw-table and secured to it; of a rotary turn -table arranged above the said saw-table and provided with a pocket for the block to be sawed, two stationary trackrings supported from the said frame over the said turn-table and provided with raised portions at prearranged points, hangers which run on the said track-rings, dogs which slide in holes in the lower parts of the said hang ers and which engage with the end portions of the said block, a grooved cam supported from the said frame, and a radially-slidable arm provided with a roller at one end which runs in the groove of the said cam and having the said dogs pivotally connected to its other end. I

In testimony whereof I aifix my signature in presence of two witnesses.
